Parts of large plate-shaped hole bit size measurement has been a technical difficulty. High-accuracy survey of large plate-shaped workpiece, has been through large-scale special measuring caliper measurements.This method have large limitations and is operate inconveniented. The precision for this detection method dependent on the skills of the workers, could not be guaranteed.That use of visual imaging technology to test the large workpiece size online and detection of the quality of whether. The device composition by the console, mechanical transmission, photoelectric detection system, lighting system and computer digital image processing system.The detection principle is controlled CCD photoelectric detection system along the rail for uniform linear motion by the console to measured holes large plate-shaped spaces workpiece size measurementThrough digital image processing technology and image mosaic technology to process the image of photoelectric detection system collected Object-image telecentric beam path design, and use the written procedures to detect the shape and position and the results can be real-time display in computer. In order to achieve the non-contact measurement on a large plate-shaped hole bit size workpiece.The device is a new and huge potential detection device for the plate-type workpiece hole shape and position. Settled the test limite in this area for a long time.In terms of development is a breakthrough. On the measurement accuracy, control methods, technical methods have a positive impact.
